[BLE] Best way to display notified values

Issue: Update value on UI on received a notification via BLE.

What is the best way to display a BLE value on UI (html handlebars)?
Is ngZone really necessary? And how to use it correctly in this case?
I think it’s better to control the refresh time. e.g. setInterval? Instead of involking UI on every notify-event. At last, the values comes every 50ms. Up to 10 values on different times.

How would you implement that?
I look forward to your suggestions.
What is the best way to do this?
